To all whom it may concern: r

Be it known that I, JAY-E. BLACK, a citizen of the United States, residing at Elwood, in the county of Madison and State of Indiana, have invented 'certain'new and useful Improvements in Pot-Furnaces, and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in self-melting pots for use in glass manufacture and the object in view is to produce a plurality of furnaces in which movable carriers are mounted, adapted to receive the raw material to be melted as it passes through one furnace and shifted to a position underneath the blowing machine, suitable gas burners being provided to prevent the molten glass from cooling too quickly while being drawn from the pot and blown.

The invention comprises various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a view in elevation of a furnace, partly in section. Fig. 2 is a view in elevation of a carrier, showing in cross section tracks upon which the same moves. Fig. 3 is a top plan view of the carrier. Fig. 4 is a cross sectional View on line 4:-4 of Fig. 2, and Fig. 5 is a top plan view with the upper portion of the furnace removed and showing the arrangement of the tracks and carrier.

Reference now being had to the details of the drawings by letter, A, A designate furnaces, mounted one over each of the tunnels B and within the tunnels are mounted upon suitable abutments the tracks C which are grooved upon the upper surfaces, said tracks intersecting as shown for convenience in shifting a carrier in and out of the furnaces. A carrier, designated by letter E, is provided with legs K which are recessed upon their under surfaces for the reception of the ball bearings N which run in the grooves I Specification of L etters latent.

of the tracks and each carrier. has holes H therein, and F designates pots which are mounted one in each of said holes, adapted to contain the raw material which, after passing through the furnace,'becomes molten glass 'to be blown.

Endless conveyers, designated by letter L, pass about sprocket wheels J fixed to the shafts J and mounted to travel in the direc tion of the arrow, shown in Fig. 5, are two chains R on the opposite sides of the kiln and each has buttons R projecting from certain links of the carrier.

Each carrier has notched lugs S, as shown in Fig. 4, which are adapted to be engaged by lugs B when the carrier is beingmoved from one furnace to the other by the lugs R engaging said lugs S, while other lugs, designated by letter Q, having notches Q there in, project down throughthe sides of the carrier and are designed to be engaged by lugs L upon the conveyers L. Suitable gas burners, designated by letter T, are positioned so that the heat therefrom will keep the glass in molten condition while being blown by the machines.

In operation, the carriers are'located at the lower left hand corner of Fig. 5, in .which position the receptacles upon the carrier are adapted to receive the raw material to be melted, after which the carrier advances, as shown in solid lines in Fig. 5 in the direction of the arrow and, while passing through the furnace which may be of any length, the material will be melted and the molten glass in the pots, when the carrier reaches the position shown in dotted lines at the upper left hand corner of Fig. 5, will be in readiness to be drawn by the blowing machines, after which, owing to the curved tracks projecting at right angles to the length of the tracks which pass through the furnace, the carrier may be moved to the extreme upper right hand corner of the Fig. 5 where a new supply of raw material may be introduced into the pots preparatory to the carrier afterward being passed through the second furnace in the direction of the arrows and, when the carrier arrives at theposition shown in dotted lines at the lower right hand corner of Fig. 5, the material which has been previously reduced to a molten state while passing through the furnace will be ready to be blown. When the carriers are at rest underneath the machines for blowing the glass, the gas burners T will serve to keep the glass hot While being blown.

From the foregoing, it Will be noted that, by the provision of a self-melting pot made in accordance With my invention the carriers Will make a circuit through the two furnaces and, be shifted from tracks at right angles to each other into the various posi.

tions described.

What I claim to be new is A pot furnace for use in glass manufacture, consisting of a plurality of furnaces and tanks, transverse and longitudinal tracks intersecting one another, carriers having legs recessed and ball bearings in said recesses movable Within the grooves in the tracks, the top of the carrier having apertures, pots engaging the same, notched lugs projecting from the carrier, endless conveyor chains With buttons thereon engaging notched lugs and adapted to move the carrier in said grooved tracks, and burners over which the carrier is adapted to rest While glass is being blown.

In testimony whereof I hereunto affix my 25 Copies of this patent niay he obtained for five cents each, by addressing the Commissioner of Patents.
